The Middlesex Co. District Attorney's office said Sabir was found to be suffering from subdural and retinal hemorrhaging, and cerebral swelling. Two days later, the child, was pronounced brain dead and subsequently died.

An autopsy by the medical examiner determined that the cause of death was blunt force head injuries, and the manner of death was homicide and not accidental.

McCarthy previously pleaded not guilty to assault and battery on a child causing substantial bodily injury.

She was jailed in lieu of $500,000 in bail while authorities awaited the child's autopsy results.

McCarthy's lawyer, who couldn't be immediately reached Friday, had protested the high bail and said his client was "an innocent person sitting in jail."
